The phrase "a rigid ground" is correct and usable in written English.
It can be used in contexts discussing stability, firmness, or a solid foundation, whether literally or metaphorically.
Example: "The construction project requires a rigid ground to ensure the building's stability and safety."
Alternatives: "a solid foundation" or "a firm base".
This equation models a simple electrostatic Micro-Electromechanical System (MEMS) device consisting of a thin dielectric elastic membrane with boundary supported at 0 above a rigid ground plate located at −1.
For rails attached to a rigid ground or located at a certain distance above it, the influence of the ground is examined in terms of the radiation ratio and longitudinal directivity.
When a voltage is applied between two electrodes consisting of a rigid ground and a deformable rectangular plate that has two parallel free edges, and one movable edge and one fixed edge, the plate bends under the electrostatic force generated in it.
Contact of a circular ring with a flat, rigid ground is considered using curved beam theory and analytical methods.
Monofrequency excess attenuation results for propagation from a point source above rigid ground to a receiver above absorbing ground are discussed.
A boundary element model also validated in previous work is applied to predict the sound pressure level on a reference surface around a tyre placed on rigid ground as function of the modal composition of the tyre vibrations.
The calculation simulates the deformation of a 55 gallon cask during and after an edge impact form a height of 1.2 m, falling at a 30° incline onto rigid ground.
The casks meet safety requirements that govern how they respond to an accidental drop onto rigid ground.
Since the study of conical rods has recently attracted some interest in various fields, the impact analysis for a conical rod falling against the rigid ground is discussed in this paper in detail and some symbolical results computed by computer algebra are presented.
An analytical model for a compliant non-pneumatic tire on frictionless, rigid ground is presented.
